‘Doctor Who’: What was the best episode of season 10?

“Doctor Who” aired its season 10 finale on Saturday, July 1, concluding a season that introduced a new companion, Bill Potts (Pearl Mackie), and set the stage for actor Peter Capaldi‘s departure as the title character, a millennia-old Time Lord who travels through space and time. Emmy-winner Steven Moffat has been the showrunner since 2010, and he too is on his way out. Their last hurrah will be the Christmas special that airs at the end of the year, after which Chris Chibnall (“Broadchurch”) will take over a showrunner and an as-yet-unknown actor will take Capaldi’s place to become the 13th Doctor in the show’s 54-year history.
